4.2Mtr X 47 X 200mm C24 Treated Regularised KD Carcassing Timber
Strength grading and structural use
This timber is strength-graded to C24 standards, which indicates it meets specific load-bearing requirements. C24 grade timber is suitable for floor joists, roof battens, stud walls, and structural framing applications. The regularised section (planed to consistent dimensions) aids installation and ensures uniform bearing surfaces.
- C24 grade delivers superior load-bearing performance for structural work
- Regularised finish provides consistent dimensions for easier fitting
- Kiln-dried to improve stability and reduce movement on site
Treatment and durability
The pressure-applied preservative treatment protects the timber against rot, fungal decay, and insect attack. This makes it suitable for applications where moisture exposure or external conditions are a concern. The treatment is integral to the timber and does not require additional on-site application.
- Pressure-treated for rot and decay resistance
- Suitable for both internal and external applications
- Protection against fungal decay and insect attack
Purchasing and storage
This product is supplied as a single 4.2 metre length in 47×200mm section. When ordering, consider the number of lengths required for your project and any cutting waste. Store the timber in dry conditions on level ground, supported at intervals to prevent sagging or warping. Keep treated timber away from areas where it may come into contact with food preparation surfaces.
- Supplied as 4.2 metre lengths; calculate quantities based on project requirements
- Store on level ground with adequate support to prevent distortion
- Keep in dry conditions to maintain stability
Fixing methods
C24 carcassing timber is typically fixed using nails, screws, or bolts depending on the application. For floor joists and structural framing, use appropriate fasteners rated for the load conditions. Ensure fixings are spaced according to building regulations and structural design requirements. Pre-drilling may be necessary to prevent splitting, particularly near the edges of the timber.
- Use nails, screws, or bolts appropriate to the structural application
- Follow building regulations for fastener spacing and sizing
- Pre-drill near edges to minimise splitting risk
